Teachers and principals have been asking for this. There are "Assessment Types" that use the same set of Assessment Skills from term to term, and many of the marks remain the same, or will adjust by a plus or minus sign (for example).
It would be much less tedious and time-consuimg if teachers could have these marks pre-populated from the previoud term and use that as a base to edit marks for the current term.
Please look into implementing this!
